The symptoms are that I open a Live program with a single M4L patch in it, and after I use it for a little my computer keyboard ceases to work until I reboot.
I'm about a week away from an important show, so I'm sort of freaking out over this as it forces me to reboot each time it happens.
I had this issue in the past when I was running Live and M4L on a small window size (when I was trying to make a movie to demonstrate some point) but now I get it all the time for one sequence and one M4L live patch in particular.
I'm downloading a brand-fresh copy of both Max and Live in case that'll fix it - but I haven't changed a thing in my installation, it's a desperate attempt to do something useful.
The M4L patch isn't particularly complex (by my standards) and seems to work perfectly well, even once the keyboard has stopped working. And the last time this was happening, I hadn't even written this new patch.
Any help desperately requested!
